+1 for the warning, find and rm is potentially a very dangerous combination.

Will fill your terminal with lots of warnings of "find: '.../.svn': No such file or directory". The directories get removed, but you can avoid the warnings with -depth (see my answer).

without -depth, the command will attempt to recurse into the .svn directory after it has deleted it, resulting in error messages.

without -type d (which limits your search to directories), you would also delete files of the given name. (Most likely you won't have any, but you shouldn't take chances when doing a combination of "find" and "rm".)
